3.6.4
Wiring the FACP line
The following examples show how control via reset input as described in Sec.
3.6.3.2 is implemented. If wiring with control via
the voltage supply is necessary, the control circuit in the following figures can be implemented as described in Sec.
3.6.4.1
Circuitry on zone detection via Al / St relay
•
For circuitry on zone detection lines, actuation of the auxil-
iary relay is, as a rule, from the line plus. A condition for
this, however, is that the line plus also switches for “Zone
ON/OFF” and “Reset” (see
Fig. 23, C)
).
•
Circuitry as shown in
Fig. 23, B)
is used exclusively when
the FACP line is to operate with
2-detector dependency
(
V-Al
/
H-Al
) from smoke sensors I and II. For that purpose
the FACP line is programmed for 2-detector dependency.
The ASD has
two
sampling pipes which cover the
same
monitoring area
, or only
one
, and
merging
takes place
before the ASD on tube input I and II.
•
When wiring as shown in
Fig. 23, C)
,
Al I
and
Al II
can be
evaluated in the FACP as independent zones from two in-
dependent monitoring areas. A
2-line dependency
can
also be programmed in the FACP. In that case, the same
applies as in
B)
; both sampling pipes from one monitoring
area, or merging of a sampling pipe on tube input I and II.
•
If wiring as in
Fig. 23, C)
is used, the control signal for the
reset input can no longer be picked up from the line plus;
instead, a software output has to be created with the fol-
lowing programming:
Output switches when:
Line/Zone A or B “Reset”
or:
Line/Zone A and B “Off”
